| The classifications of nonoxidative haircolor are demipermanent and permanent. | False |
| Viscosity measures the concentration and strength of hydrogen peroxide. | False |
| Powdered off-the-scalp lighteners contain persulfate salts for quicker and stronger lightening. | True |
| A presoftener acts like a stain to the hair. | True |
| Hair that looks gun-metal gray is ready to receive color. | False |
| The natural coloring pigment found in the cortex layer of the hair is: | melanin |
| Hair texture is determined by the diameter of individual hair: | strands |
| Fine hair takes color faster and can look darker because the melanin granules are grouped: | more tightly |
| The hair type with a large diameter that can take longer to process hair color is: | coarse-textured hair |
| The ability of the hair to absorb liquids is referred to as: | porosity |
| When the cuticle of the hair is lifted and the hair is overly porous and absorbs color quickly, the hair porosity is defined as: | high |
| The melanin that gives black and brown color to hair is: | eumelanin |
| The system used by colorists to analyze the lightness or darkness of a hair color is: | the level system |
| The darkest hair colors in the level system are identified as being a level: | 1 |
| The system used for understanding color relationships is the: | law of color |
| Fundamental or pure colors that cannot be achieved from a mixture are: | primary colors |
| The primary color that brings depth or darkness to any color is: | Blue |
| When all three primary colors are present in equal proportions, the resulting color is: | brown |
| A color obtained by mixing equal parts of two primary colors is a: | secondary color |
| A color achieved by mixing equal parts of a secondary color and its neighboring primary color on the color wheel is a: | tertiary color |
| Primary and secondary colors that are positioned opposite each on the color wheel are: | complementary colors |
| The hue or balance of color seen in the hair is referred to as: | Tone |
| Tones can be described as cool, warm, or: | neutral |
| Colors that can look deeper than their actual level are: | cool tones |

| Demipermanent colors are also known as: | no-lift deposit-only colors |
| The coloring products that are regarded as the best for covering gray hair are: | permanent haircoloring |
| Dye precursors that combine with hydrogen peroxide to form larger, permanent dye molecules are called: | aniline derivatives |
| Natural, vegetable, and metallic hair colors are also known as: | gradual colors |
| Haircoloring products that change color gradually by progressive buildup and exposure to air contain: | metal salts |
| The most commonly used developer in hair color is: | hydrogen peroxide |
| The standard volume of hydrogen peroxide used to achieve most results with permanent haircolor is: | 20 volume |
| Chemical compounds that lighten hair by dispersing, dissolving, and decolorizing the natural pigment are: | hair lighteners |
| The process where the hair is prelightened and then toned is: | double-process application |
| Decolorizing the hair’s natural pigment allows the colorist to create the exact degree of: | contributing pigment |
| Hair coloring products that are used primarily on prelightened hair to achieve pale and delicate colors are: | toners |
| During the process of decolorizing, natural hair can go through as many as: | 10 stages |

| A predisposition test is generally conducted behind the ear or: | inside the elbow |
| The process that lightens hair and deposits color in one application is a: | single-process hair coloring |
| Examples of single-process permanent coloring applications are virgin color applications and: | color retouch applications |
| Overlapping hair color on previously tinted hair can cause breakage and create a visible line of: | demarcation |

| Lighteners that have a thicker consistency and give more control during scalp application are: | cream lighteners |
| Powdered persulfate salts added to haircolor to increase its lightening ability are: | activators |
| The part of the hair shaft between the scalp and the hair that has been previously colored is the: | new growth |
| The coloring technique that involves coloring some strands of hair lighter than the natural color is: | highlighting |
| The technique of coloring strands of hair darker than the natural color is: | lowlighting |
| In the weaving technique, selected strands are picked up from a narrow section of hair with a: | zigzag motion |
| The technique using a free-form of painting hair lightener directly on clean, styled hair is: | baliage |
| The process of treating gray or very resistant hair to allow for better penetration of color is: | presoftening |
| You should NEVER apply hair color to a client if the scalp has any obvious signs of: | abrasions |
| First step of double-process haircoloring | Prelightening |
| Refers to the first time the hair is colored | Virgin application |
